BARREL-HEAD-RELEASING IMPLEMENT.

Specification of Letters Patent.

Application filed January 3, 1911.

Patented Nov. 14, 1911.

Serial No. 600,421.

T 0 all whom if may concern:

Be it known that I, SARAH L. A. KILLIoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Barrel-Head-Releasing 11nplements, of which the following is a specification.

The object of my invention is to provide a tool or implement of novel and simple construction adapting it to be used upon sheet-metal containers, such as the corrugated barrel shown and described in my application for Letters Patent, Serial No. 600,420 filed on the 3rd day of January, 1911, for releasing the heads thereon.

In the accompanying drawing, Figure 1 is a top view of the body-portion of a corrugated sheet-metal barrel showing my improved implement operatively applied thereto; Fig. 2 shows a headed end of the barrel in elevation with myimproved implement in operative position thereon and showing the parts of the implement in the relative positions to which they are brought by operating it; Fig. 3 is a broken view in elevation of the implement with the parts in their normal relative positions; Fig. 4c is a section on line 4:, Fig. 3, and Fig. 5 is a broken section on line 5, Fig. 2.

The container is shown as a barrel 6 of ordinary bilge type, having its body-portion 7 formed of a sheet of steel corrugated lengthwise of the barrel and provided about its ends, as indicated ofone end in Fig. 5, with a circumferential series of external teeth 8 projecting outwardly from the corrugations, being preferably formed by being struck up from the metal sheet. The sheet-metal covers or heads, of which one is shown at 9, are formed with flanges 10 to surround the end-portions of the barrelbody and interlock, to fasten them against removal, with the projections 8, as through the medium of a circumferential in-turned lip 11 on each head-flange, into the path of which the projections extend by forcing the cover over them into place to cause the outward spring of the resilient body, after the lip has cleared the projections, to eifect the desired locking of the cover in place by opposing the projections, as an abutment, in the path of the lip; all as described in my Copies of this patent may be obtained for said concurrent application. With a head 9 thus fastened, its release may best be etfected by contacting the body 7 to withdraw the projections 8 from obstructing the lip 11; and my implement is designed for that purpose by the following-described construction thereof: A band 12, which may best be formed of a single length of adequately strong or heavy wire bent into annular shape, whereby it forms a resilient ring with lapping ends, has one end bent back upon itself and fastened, as at 13, to form a loop 14: which is again bent back to form a hook 15, the opposite end of the band being bent outwardly at a right-angle to form a pivot-pin 16 for the cam-head 17 of a lever 18, the head being thus confined be tween the back and jaw of the hook to engage the closed or inner end thereof by turning the lever.

To use the implement, it is applied about the body-portion 7 adjacent to a head 9 in the normal condition in which it is represented in Figs. 1, 3 and 4, whereupon the lever is turned to the position shown in Fig. 2, thereby forcing the cam-head against the closed end of the hook with the elfect of moving the pin along the slotted back of the loop toward the point 13 and pulling the band to tighten it about the barrel. Thus tightening the band contracts the corrugated body 7 toward the end at which the implement is applied, and in so contracting the projections 8 are withdrawn from obstructing the lip 11, thus freeing the head and permitting its removal. To release the implement its cam-lever is turned in the opposite direction, permitting the band to eX- pand to its normal condition.

What I claim as new and desire to secure by Letters Patent, is-

An implement for the purpose set forth, comprising an annular metal band tenninating at one end in a hook-forming loop and at its opposite end in a fulcrum-pin projecting transversely through the hook, and a lever provided with a cam-head eccentrically fulcrumed on said pin to work within and against the hook.
